In a processing plant, a chemical tower has a liquid which is vaporized. However, if the vapor in the tower reaches 150°C, an alarm needs to be generated so that safe shutdown of that system of the plant may be initiated. An RTD will be used to measure the temperature of the vapor. The RTD will generally operate between 80° to 175°C and has a resistance of 220? at 20°C. The fractional change in resistance per 1°C is 0.0040. The dissipation constant is 25mW/°C. Design a circuit to activate an LED alarm when the temperature reaches 150 °C. The error should not exceed +/-1°C. Use a single supply voltage.
Design a counter with the sequence 0-3-2-1-0 utilizing two flip flops. Flip flop A (MSB) is to be a JK type and Flip Flop B (LSB) is to be a RS Flip Flop.
What is the equivalent input noise resistance of an amplifier known to produce 20 V of equivalent input noise over a bandwidth of 750 kHz
Suppose a DC power source with a voltage of 50 volts is connected to a 10-ohm load. How much power will this load dissipate. Now suppose the same 10 ? load is connected to a sinusoidal AC power source with a peak voltage of 50 volts.
In a processing plant, jars on a conveyer belt are cleaned out with a high-pressure air jet just prior to being filled (Figure Below). When a jar approaches the cleaning station, it activates a switch (with both NO and NC contacts).
An x-y plane separates two materials. Material 1 covers z 0 region. There is no surface current or charge on the boundary between the two materials.
introin this design you are going to use a chain of flip-flop to implement a shifter register.design requirementwhen
